Any tips for getting stems from Logic Pro 9 to Reaper?

[DreamDisease]

Hi guys, I'm trying to upgrade my mac from OS 10 to OS whatever the latest version is. Before I used reaper, I used logic pro 9. Now I want to move all my projects I started in LP9 to Reaper because it's so much better.

So, what's the fastest best way to do this? I've already tried just getting dry stems from ONE song, but once I brought it into Reaper it didn't sound the same. And that's just ONE project. I have hundreds.

Oh, and does anyone know a free sampler that can handle EXS24 patches without having to reload it every time you open the project? Currently I use AUSampler to emulate Logic's instruments in Reaper, but the downside is I have to reload the patch each time or I get this sine wave mixed with the sample.

Any help appreciated, thanks
